Rules for Naming Binary Ionic Compounds Containing a Metal Ion With a Variable Charge. A binary ionic compound is composed of ions of two different elements - one of which is a metal, and the other a nonmetal. For example, iron(III) iodide, FeI3, is composed of iron ions, Fe3+ (elemental iron is a metal), and iodide ions, I- (elemental iodine is a nonmetal). Rule 1.
Naming Binary Covalent Compounds. If a binary compound is composed of two nonmetals, it is a covalent/molecular compound. Use the appropriate prefixes to name these simple compounds. Mono- is only used as a prefix on the second element in the formula. The ending for the second element is always removed and replaced with -ide. 1 = mono- 2 = di- 3 = tri- 4 = tetra- 5 = penta- 6 = hexa- 7 = hepta- 8 = octa- 9 = nona- 10 = deca-
